Genes affected

CHDH (HGNC:24288): (choline dehydrogenase) The protein encoded by this gene is a choline dehydrogenase that localizes to the mitochondrion. Variations in this gene can affect susceptibility to choline deficiency. A few transcript variants have been found for this gene, but the full-length nature of only one has been characterized to date. [provided by RefSeq, Dec 2010]

The c.1451A>G (p.K484R) alteration is located in exon 9 (coding exon 7) of the CHDH gene. This alteration results from a A to G substitution at nucleotide position 1451, causing the lysine (K) at amino acid position 484 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
